Designed for highest performance and reliability

High performance O and H isotope ratio analysis does not have to be complicated. The vario PYRO cube® perfectly adapts to your analytical demands for high temperature EA-IRMS analysis. With our blank-free pyrolysis reactor and our patented backflush technology, you no longer have to worry about distortion of your analytical results through interfering gases. Use the vario PYRO cube in combination with one of our high performance IRMS systems and enjoy highest accuracy and precision in both OH and CNS isotope ratio analysis, unmatched ease of operation, and great durability.

Reliable results in oxygen isotope ratio measurement of nitrogen-containing samples are achieved with the vario PYRO cube using a patented backflush system to remove background bleed of the pyrolysis reactor from the CO peak, resulting in complete baseline separation of the N2 from the CO peak and superior CO peak focusing.

Operating Comfort

The vario PYRO cube stands for unmatched user-friendliness. The instrument is designed for safe unattended overnight measurements. During operation, all sample positions are accessible and reloadable at any position and time. The feature-rich software and a high level of automation guarantee ease of use for all users.

Great Flexibility

The vario PYRO cube can be operated in OH or CNS mode – giving you the all-in-one instrument solution for EA-IRMS analysis of C, N, S, O, and H. Elementar‘s APT separation technology of the analysis gases results in a large dynamic measurement range – samples from the low microgram up to the two-digit milligram range can be analyzed.

Extreme Durability

The vario PYRO cube is characterized by a low consumption of consumables. The pyrolysis reactor can be used for several thousand samples, reducing maintenance effort and increasing system uptime. In combination with low carrier gas consumption, low operating costs are guaranteed.

Pyrolysis

Oxygen isotope ratio analysis relies on the conversion of sample oxygen to carbon monoxide following the temperature-dependent Boudouard equilibrium, which favors the formation of carbon monoxide over carbon dioxide with increasing temperature during pyrolysis. Therefore, a full conversion of sample oxygen to carbon monoxide requires furnace temperatures in excess of 1400 °C. The vario PYRO cube is a designated EA-IRMS interface analyzer for highly precise and matrix-independent hydrogen and oxygen isotope ratio measurement via high temperature pyrolysis at 1450 °C.

Advanced Purge and Trap (APT)

Elementar’s proprietary APT technology is a unique high-performance chromatographic technique for the determination of nonmetal elements. The fractionation-free APT technology is capable of resolving C/N ratios of up to 7000:1 and C/S ratios of up to 5000:1. Distinct peak separation assures reliable and trouble-free data acquisition. Data analysis can be easily automated for larger sample amounts while maintaining the highest possible data quality. Elementar’s unique APT columns are optimized to provide unmatched robustness and longevity compared to GC columns. Furthermore, they can be loaded up to 250-fold higher, resulting in outstanding sample flexibility. Thus, customers enjoy industry-leading accuracy, sensitivity, and versatility.

Ease of Use

The vario PYRO cube is optimized to significantly simplify daily routine operation. Clearly arranged, easily accessible components, as well as a furnace that slides out, minimize maintenance efforts. The tool-free clamp connection system ensures a reliably leak-tight instrument at any time. Thus, customers can enjoy smooth analyses and confidence in their results.
